qBRIDGE-206
is a high performance G.SHDSL.bis modem operating in the "Bridge" mode. It provides a symmetrical
data rates up to 5.7 Mbps on a single pair of copper line and up to 11.4 Mbps on two twisted-pairs.
It supports TC PAM-32/16 line coding.
With its rate adaptive features, modem provides longer reach on transmission distance according to the line conditions
up to 7 Km.

With DIP-switches's configuration only Annex F&G specification and TC PAM-32 line coding are available (factory setting).
For detailed setup qBRIDGE-206 supports HTTP interface.
Using HTTP interface you can choose a line coding (TC PAM-32 or TC PAM-16) and G.991.2 Annex (Annex F&G or Annex A&B).
It's possible also to select line speed more precisely than using DIP-switches.
